Embedded Flash Protection with Hardware Root of Trust and Lite Crypto Engine
Overview
PUFef is the extension function available for PUFrt, extending the Hardware Root of Trust to protect critical assets in the embedded Flash. PUFef can widen an SoC’s secure boundary based on our highly reliable PUF technology widely available across all major foundries.
Key Features
- PUFef is designed to protect embedded flash with the hardware root of trust and a lite crypto engine of RC6. The RC6 provides the right level of security with minimal area cost. Attackers would have destroyed the embedded flash first before cracking the crypto engine.
